TSMC: process push, big margins

Taiwan Semiconductor Manufacturing Co. is selling customers on a simple pitch: smaller, more efficient chips now come with unusually fat margins for the factory making them. (tsmc.com 1) (tsmc.com 2) At its North America Technology Symposium on April 23, 2025, TSMC unveiled A14, the process node planned for volume production in 2028. The company said A14 should deliver up to 15% higher speed at the same power or 30% lower power at the same speed than N2. (tsmc.com) TSMC also said A14 should increase logic density by more than 20% versus N2, which is scheduled to enter volume production later in 2025. It paired that process update with NanoFlex Pro, a design approach meant to let chip customers trade off speed, power use, and area more precisely. (tsmc.com) For artificial intelligence chips, the transistor is only part of the problem. TSMC said it will bring a 9.5-reticle version of CoWoS packaging into volume production in 2027 so customers can combine 12 or more stacks of high-bandwidth memory with leading-edge logic in one package. (tsmc.com) That matters because AI systems are increasingly limited by how much memory they can place next to the processor, not just by transistor size. TSMC also said its SoW-X wafer-scale system is scheduled for volume production in 2027 with 40 times the computing power of its current CoWoS solution. (tsmc.com) The financial backdrop is just as striking. In first-quarter 2026 results, TSMC reported $35.90 billion in revenue, gross margin of 66.2%, and operating margin of 58.1%, all above its own guidance ranges. (tsmc.com) Those margins show how much pricing power TSMC still has at the top end of chipmaking, where only a handful of companies can build the most advanced processors. TSMC’s second-quarter 2026 guidance called for revenue of $39.0 billion to $40.2 billion and gross margin of 65.5% to 67.5%. (tsmc.com) The company is building more of that capacity in the United States. On March 4, 2025, TSMC said it would add $100 billion to its Arizona plans, bringing total planned U.S. investment to $165 billion, with three new fabs, two advanced packaging facilities, and an R&D center. (tsmc.com) TSMC said the Arizona site had been in volume production since late 2024, and the expansion is aimed at completing a domestic AI supply chain in the United States. The company named Apple, Nvidia, Advanced Micro Devices, Broadcom, and Qualcomm among customers tied to that push. (tsmc.com) Put together, the message from TSMC is that the next gains in AI chips will come from both finer transistors and bigger, denser packages — and customers will keep paying up to get them.
